What You’ll Find Here


The leading cause of accidental death in Marin County is overdose. This data is intended to track trends and provide information for shared understanding and action across our County. OD Free Marin strives to prevent overdoses through data driven strategies and community collaboration.

Non-Fatal Overdose


A non-fatal overdose is a sign of unsafe drug use and risk for future fatal overdose. Tracking non-fatal overdose events provides valuable insights to guide prevention strategies. Outreach to overdose survivors is a proven approach to limiting mortality. Spikes in non-fatal overdoses may signal the presence of particularly potent substances in the drug supply, including fentanyl.

Data notes

Marin Health & Human Services (HHS) uses Emergency Medical Services (EMS) records from all 911 calls to identify suspected drug overdoses. A single overdose can include multiple substances. These records include both intentional and unintentional overdoses. Results are updated in the first week of each month.

* Data for the current year is complete as of the data refreshed date. ** Counts are not mutually exclusive, meaning one overdose event can include multiple types of drugs. *** Race/Ethnicity information became a mandatory field starting 2021.

Fatal Overdose


Fatal overdoses are increasing nationally and in Marin. OD Free Marin sees overdose deaths as preventable. Our aim is to reverse this trend by raising awareness, coordinating action and directing resources to prevent overdose and save lives.

Data notes

Death investigations conducted by the Marin County Sheriff-Coroner for drug overdoses may take six months to a year, leading to delays in tallies of fatal events. Therefore, 2022 data will not be complete until the end of 2023. These records include both intentional and unintentional overdoses. Results are updated the first week of each month.

* Counts are not mutually exclusive, meaning one overdose event can include multiple types of drugs.

Buprenorphine Prescription Rates, 2012-2022


Many residents with opioid use disorder lack access to proven therapy. Increasing access to Medication Assisted Treatment (MAT) is an OD Free Marin goal. Buprenorphine is the first line therapy for opioid addiction and is proven to reduce the risk of opioid overdose. Buprenorphine can be prescribed by a licensed provider in various settings, including primary care clinics, community hospitals, emergency departments, health departments and correctional facilities.

Tracking buprenorphine prescriptions allows us to measure progress in removing barriers to MAT county-wide.

Buprenorphine prescriptions are reported by dispensing pharmacies to the California Prescription Drug Monitoring Program (PDMP). Marin County Department of Health and Human Services updates results here semi-annually.

Opioid Prescription, Marin County, 2008-2022


Safe and appropriate prescribing is a goal of OD Free Marin. Historically, opioid overprescribing fueled the opioid overdose epidemic. Tracking opioid prescriptions (by morphine equivalent) in Marin allows us to see trends in “opioid prescription burden,” or the negative health impacts of overprescribing over time. Additional detail can be found on the California Opioid Overdose Surveillance Dashboard.

Confiscated Drugs, 2020-2022


One driver of the overdose epidemic is the increasing and unpredictable presence of highly potent substances in the illicit drug supply, such as the synthetic opioid fentanyl. This chart, supplied by the Marin County Sheriff, translates the drugs confiscated in Marin into the number of potential lives saved, based on the weight of the substances and lethal doses.
